-v, --version Print the currently installed version of AirRAC on the standard output.

-h, --help Produce that message and show usage.

-b, --builtin The sample BOM tree can be either built-in or parsed from an input file. When that option is selected, an input file must then be given with the -y/--yield option. When that option is not selected, the airrac program builds a simple use case directly from internal hard-coded parameters (yield rules).
